Step 1: Create a release

On the left menu, select Release management > Android Instant Apps. You'll see three track types.

Development: Use the development track for quick deployment of your instant app during development. Before you can publish your instant app, you must upload an APK of your installed app on the App releases page.

Pre-release: Use the pre-release track to send out a release candidate to testers. Before you can publish your instant app, your installed app must be published to alpha, beta, or production on the App releases page.

Production: Use the production track for the public release of your instant app. Before you can publish your instant app, your installed app must be published and have a production APK on the App releases page.

Next to the release type you want to create, select Manage. For more information about setting up each track type, select the relevant section below.

Add email addresses separated by commas or click Upload CSV. If you use a .CSV file, put each email address on its own line without any commas. If you upload a .CSV file, it will overwrite any email addresses you've added.

After you create a test, you'll get a URL link to your instant app to share with your testers. After clicking the opt-in link, your testers will get an explanation of what it means to be a tester and a link to opt-in.

A user can only test one instant app release track at a time. This means if a user is testing a development release and then opts in to test a pre-release, they will automatically be removed from the development release.

If you've filled out these sections for the installed version of your app, the same information will apply for your instant app. Keep in mind, instant app availability is defined by your instant app manifest and not by your app's device exclusions.

Enter the amount of traffic you want to direct to mobile web. For example, if you enter 0.95, 95% of instant app eligible traffic will be sent to mobile web. The remaining 5% will be sent to your instant app.
